The choreography is designed starting from the couple’s embrace which is highly sensual and complex. But, the complexity of the steps does not have to do with the expression or to what is to be expressed during the dance. It is all about expressing a sensual feeling, not sexual, where the steps or figures drawn by the dancers are not the most important aspect. A perfect technique and/or synchronization are of no use at all if the facial expression of dancers is unfeeling.
Everything in Tango dancing must be united: looks, arms, hands, every movement accompanying the cadence of Tango and to what dancers are feeling which is a three minute romance between two people who might just have met and probably have no sentimental relation between them in real life. Tango goes beyond and reaches the heart of those looking on, thanks to the feelings put into the dancing and the quality of the choreography.
Every stanza, every transition, every Tango has different moments and it cannot be danced following an identical pattern. There are sad cadenzas, grand ones, in-crescendo music or in-diminuendo. They all express feelings and these feelings are what the dancers put into their bodies and feet.
